Thanks!
That is that kind of information what I would like to hear :)

Ok, found it :)
I sucessfully use that otimizer and had a quick look into the flags and did
not remeber something like 'balance' or 'quad tree' or whatever.
As german - I expect you have already identified that - I had not connected
spatialize with a quadtree ...
Aehm, I came across something in osg::Material.
The osg::Material::apply routine is the only place where glEnable is called
outside the codepath used for the osg::StateSet::setMode().
I wonder if this is a source for inconsistencies in the osg::State in the
sense that osg::State believes GL_COLOR_MATERIAL is not enabled but the
osg::Material::apply just did enable that?
Greetings
Mathias
